Common Anxiety Disorders Some of the more common anxiety disorders include: Compulsions are repetitive behaviors that help to prevent or relieve anxiety.
A person with obsessive-compulsive disorder experiences obsessions, compulsions, or both. Some researchers have suggested that damage to the hippocampus can contribute to PTSD symptoms. Serotonin is a neurotransmitter that affects sleep, alertness, appetite, and other functions.
Symptoms include increased arousal such as insomnia, irritability, difficulty concentrating, hypervigilance, or exaggerated startle response.
Inefficient processing of serotonin may also contribute to anxiety. They raise the level of serotonin in the brain by preventing it from being reabsorbed back into cells that released it. As a result, the person often avoids these types of situations.
During a panic attack, a person has symptoms such as heart palpitations, sweating, trembling, dizziness, chest pain, and fear of losing control, going crazy, or dying.
A person with generalized anxiety disorder experiences persistent and excessive anxiety or worry that lasts at least six months.
Agoraphobia involves anxiety about losing control in public places, being in situations from which escape would be difficult or embarrassing, or being in places where there might be no one to help if a panic attack occurred.
Twin studies suggest that there may be genetic predispositions to anxiety disorders. The person often avoids the feared object or situation because of a desire to escape the anxiety associated with it.
A concordance rate indicates the percentage of twin pairs who share a particular disorder. Roots of Anxiety Disorders Many different interactive factors influence the development of anxiety disorders.
Abnormal levels of serotonin can lead to mood disorders. Panic Disorder and Agoraphobia: GABA limits nerve cell activity in the part of the brain associated with anxiety. A person with this disorder persistently re-experiences a highly traumatic event and avoids stimuli associated with the trauma.
A person who has specific phobia experiences intense anxiety when exposed to a particular object or situation.
People who do not produce enough GABA or whose brains do not process it normally may feel increased anxiety. A person usually feels that the obsessions are inappropriate but uncontrollable. Panic disorder can occur with or without agoraphobia.
A person who has social phobia experiences intense anxiety when exposed to certain kinds of social or performance situations. A person with panic disorder experiences recurrent, unexpected panic attacks, which cause worry or anxiety. Biological Factors Many biological factors can contribute to the onset of anxiety disorders: Researchers believe there is a link between anxiety disorders and disturbances in neural circuits that use the neurotransmitters GABA and serotonin.
Research has shown that identical twins have a higher concordance rate for anxiety disorders than fraternal twins. People who are highly sensitive to the physiological symptoms of anxiety react with even more anxiety to these symptoms, which sets off a worsening spiral of anxiety that can result in an anxiety disorder.
Researchers typically use concordance rates to describe the likelihood that a disorder might be inherited. However, a chronic, high level of anxiety indicates an anxiety disorder.Overview.
